The R911289882 (DKR03.1-W100N-BA03-01-FW) is a Rexroth Indramat DKR series drive controller with a mass of approximately 49 kg. It is designed for systems with a rated current of 100 A and a system frequency of 50-60 Hz. The unit incorporates a built-in blower for air cooling and dissipates heat at 900 W for standard operation or 600 W when using external cooling. It features resolver feedback, digital servo feedback, an analog command interface, and operates with a control voltage of 230 V AC ±10%. The drive achieves a peak shaft power output of about 26 kW for 10 s and has a peak current rating of 71 A. The design does not include a bleeder (brake chopper) and is specified for a rigid DC bus. The power voltage frequency supports up to 800 Hz for a 4 kHz controller and 1600 Hz for an 8 kHz configuration. Proper function is ensured within an ambient temperature range of +5 to +45°C and elevations up to 1000 m.

Frequently Asked Questions

How does the analog command interface affect integration?

It allows simple connection to PLCs or control systems using standard ±10V signals. This reduces complexity but requires careful shielding against noise.

Why is digital servo feedback important in this unit?

It provides precise position and speed feedback, improving accuracy in high-performance applications. This reduces drift and enhances closed-loop stability.

Does the air cooling method limit mounting options?

Yes, it requires sufficient airflow and clearance for the built-in blower. Poor ventilation may cause overheating and derating.

What are the implications of a rigid DC bus without a bleeder?

Excess regenerative energy cannot be dissipated internally, so external braking or absorption solutions may be required. This is important for applications with frequent deceleration.

How does the DKR03.1-W100N-BA03-01-FW handle thermal stress?

The integrated blower improves heat removal, but continuous full-load operation demands good ambient cooling. High ambient temperatures may require derating.
